In the example, they talk about GBP , the n sending USD to Taiwaan , so two conversions.
Just did Bht 40k from GBP to THB, which cost me GBP 5.66 in fees, about 0.6%.
However, £21000 to Dubai cost £111. which would probably been cheaper using SWIFT, but I needed it there urgently, so 3 hours and it was there.
